Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vacuum cleaner equipped with a dust collection bag such as a paper bag.

BACKGROUND ART The structure of a conventional vacuum cleaner of this type will be described with reference to the drawings.

In FIGS. 7 to 9, 1 is a vacuum cleaner main body that includes a fan motor 2, a cord reel 3, etc., and a dust collection bag 4 such as a paper bag is installed in front of the fan motor 2. It has chamber 5. A lid 6 for opening and closing the upper opening of the dust collection chamber 5 is rotatably attached to the main body cover 7 via a rotation shaft 8 at its rear. When the user opens the dust collection chamber 5 when replacing the dust collection bag 4, the rotation shaft 8
Rotate the lid 6 so that the front part is raised upwards.

Further, the front of the lid 6 has an intake port 11 into which a rotary elbow 10 to which a hose 9 is fixed is inserted. A rotary elbow 10 is fixed to this intake port 11, and a disk 12 is provided so as to be freely rotatable. The disk 12 is supported above by a lid 6 and laterally by an inner lid 13. Further, this disk 12 is fixed to a rotating body 14 with screws and rotates at the same time, and is supported by an inner cover 15 from below.

Further, reference numeral 16 denotes an intake port gasket fixed to the inner lid 15, and is configured to be pressed against the flap of the dust collection bag 4.

Problems to be Solved by the Invention In such a conventional vacuum cleaner, when the user opens the lid 6 to replace the dust collection bag 4, the lid 6 rotates upward about the rotation axis 8. The state will be as shown in FIG. At this time, some of the dust sucked in from the hose 9 and rotating elbow 10 does not completely enter the dust collection bag 4 and remains inside the air intake port 11, which falls downward when the lid 6 is opened. ,
This will accumulate inside the dust collection chamber 5. However, with this structure, the dust collection chamber 5 is small and deep, making it difficult to reach deep inside and cleaning it. Further, the dust accumulated in the dust collection chamber 5 passes through the fan motor 2 and is discharged to the outside of the cleaner main body 1.

The present invention solves these problems and aims to provide a sanitary vacuum cleaner that does not pollute the inside of the dust collection chamber.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a vacuum cleaner body which has a built-in fan motor and a dust-collecting chamber for installing a dust-collecting bag on the suction side. a lid whose rear portion is pivotally supported on the vacuum cleaner body so as to open and close an upper opening of the dust collection chamber, and a lid having a front downwardly sloped surface forming an air intake port; It is equipped with a pair of support plates that support the opening of the dust collection bag in parallel with the sloped surface of the lid, and of the pair of support plates, the rear support plate has a concave part that is recessed one step further from the outer periphery. Furthermore, the rotating shaft is removably supported by a pair of support ribs formed on the cleaner body.

Function With the above-described configuration, the present invention is capable of keeping the inside of the dust collection chamber clean by catching the dust falling from the intake port on the support plate, improving maintainability and also being effective in terms of hygiene. .

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 to 6, 31 is a vacuum cleaner body that includes a fan motor 32, a cord reel 33, etc. In front of this motor 32 is a dust collection chamber in which a dust collection bag 34 such as a paper bag is attached. It has 35. A lid 36 that opens and closes the upper part of the dust collection chamber 35 is rotatably attached to the main body cover 37 via a boss 38 at its rear. Also, lid 3
6 is sloped downward from the center to the front, and the front end is connected to the vacuum cleaner body 31 by a buckle 39.
is fixed.

The mouth plate 41 of the dust collection bag 34 is set parallel to the lower part of the slope of the lid 36, and its lower and upper parts are supported by support plates 40 and 42. One end of each of these support plates 40 and 42 is connected to the vacuum cleaner main body 31.
There is a pivot on the. Here, the upper surface of the support plate 42 located at the upper position has a concave surface portion 43. More specifically, the support plate 42 has rotating shafts 44 formed at both ends thereof and is detachably attached to a support rib 46 of a partition wall 45 that separates the fan motor 32 of the cleaner body 31 from the dust collection chamber 35 . Further, 47 is a spring, which supports the mouth plate 41 by always urging the supporting paperboard bag support 42 downward.

Further, the front of the lid 36 has an intake port 50 into which a rotary elbow 49 to which a hose 48 is fixed is inserted. A rotating body 51 that rotates together with the rotating elbow 49 is provided inside the intake port 50 . The rotating body 51 has an inner lid 52 on its lower side and a rotating body supporting rib 53 formed integrally with the lid 36 on its side.
Each is supported by The rotating elbow 49 passes through the intake port 50 and is fixed to the rotating body 51 so as to rotate 360°.

An inlet gasket 54 is provided at a portion of the inner lid 52 corresponding to the inlet 50 to provide air tightness with the opening plate 41 of the dust collection bag 34.

In the above configuration, when the lid 36 is opened to replace the dust collection bag 34, the lid 36 is moved to the lid rotation boss 38.
It rotates around , resulting in a state as shown in FIG.

At this time, some of the dust sucked in from the hose 48 and rotating elbow 49 does not enter the dust collection bag 34.
Some things stay in the air intake port 50 and fall downward when the lid 36 is opened. However, in the structure of this embodiment, since the support plate 42 is provided with the large concave surface portion 43, the intake port gasket 54
The dust that falls further does not fall into the inside of the dust collection chamber 35,
Most of it rests on the concave surface portion 43 (arrow in FIG. 6).
Therefore, the irrational drawback that the inside of the dust collection chamber 35 becomes dirty is eliminated.

Furthermore, since the support plate 42 can be removed by pushing open the support ribs 46 by hand, if dust accumulates in the concave portion 43 as described above, it can be removed and washed with water, making maintenance very easy. It is what it is.

Furthermore, even if the concave surface part 43 is cleaned with dust on it, this part will be damaged by the inner lid 52 and the support plate 4.
Since it is a narrow space sandwiched between 2 and 2, the air flow is not strong in other parts, and the air is stagnant, so there is no inconvenience such as dust being blown away. Therefore, the inside of the dust collection chamber 35 is not contaminated.

Moreover, since dust does not enter the inside of the dust collection chamber 35, it passes through the fan motor 32 and
1.It is effective in terms of hygiene as it will not be discharged to the outside.

Effects of the invention As described above, according to the invention, by providing the support plate that supports the mouth plate of the dust collection bag with a concave surface, dust that falls from the intake port is prevented from falling into the inside of the dust collection chamber. The interior of the dust collection chamber can be kept clean and maintenance efficiency can be improved. It is also effective in terms of hygiene, such as not polluting the exhaust air.
